From the 3M website: "3M™ Marine Adhesive Sealant 5200 is a one-component, high-strength, moisture-curing, gap-filling polyurethane for permanent bonding of wood..." 3m.com/3M/en_US/p/d/b40066983/ However, while it doesn't specifically call out metal, I would think that it would at least create a matching set of threads that would give the insert plenty to hang on to. Try it; it can't hurt.
 
A little epoxy mixed up to peanut butter consistency should work too. You have experience with that I believe?

Are you talking about the same epoxy that works for carbon fiber parts? I do have some of that around.
 
Yep, add silica or wood flour to thicken, same as if you were filleting a sponson on a hydroplane.
 
The threads are broken off of the nut. You should be able to insert a new one and it should hold. Another way is to wood glue tooth pick in the hole to add wood to the wood step. If the T nut is behind the step or on the back side, you can get a proper T nut and install it and move on. If it was screwed in from the top and the screw also from the top, it was installed wrong to begin with. 26 years as a in home furniture repair tech, I have seen a lot of out of country furniture made that way. The nut on the wrong side of the parts to be fastened. It will hold it in place but has no strength to hold tight.

Or you can epoxy it and hope it holds tight.

I couldn’t get the 5200 to harden. I used some two part epoxy and it appears to be fine
 
That's odd. How long did you let it cure for?

Three days before I gave up on it.

What was the ambient temperature? 5200 won’t cure at all below 40 degrees and gets temperamental below 60. Curing can also be delayed if humidity is very low.

The high curing temperature feature is helpful if you want to store it long term. Put it in a ziplock and store in the freezer.
 
Temps were in the 70’s. Low humidity. I tried laying a wet towel over it for a day
